“…Electric muscle stimulation (EMS) has been successfully applied in patients affected by hemiplegia and subsequent shoulder instability 19 after a stroke and had proved more effective than physical therapy or transcutaneous electrical nerve stimulation in randomized controlled trials. 6 , 40 In a previous pilot project, EMS was successfully applied to counteract the presumed muscle hypoactivity causing patients to experience PP-FSI.…”

Shoulder-Pacemaker Treatment Concept for Posterior Positional Functional Shoulder Instability: A Prospective Clinical Trial

et al. 2020

Background: Pathological muscle activation patterns of the external rotators and periscapular muscles can result in posterior positional functional shoulder instability (PP-FSI). In several patients, physical therapy and surgical treatment are not successful. Purpose: The shoulder-pacemaker treatment concept was evaluated prospectively in patients with PP-FSI and previously failed conventional therapy attempt. Study Design: Case series; Level of evidence, 4. Methods: A negative selection of 24 consecutive cases of noncontrollable PP-FSI in 16 patients with previously failed conventional therapy were included in this prospective study. The shoulder-pacemaker treatment consisted of an electrical muscle stimulation–based therapy protocol with 9 to 18 one-hour treatment sessions. Two patients were excluded because of nonadherence to the training schedule, leaving a final study cohort of 21 cases in 14 patients. Follow-up included assessment of clinical function, impairment during daily activities and sports, satisfaction, Western Ontario Shoulder Instability Index (WOSI), Rowe score, and Subjective Shoulder Value at 0 weeks, 2 weeks, 4 weeks, 3 months, 6 months, 12 months, and 24 months after intervention. Results: WOSI, Subjective Shoulder Value, and Rowe score showed a highly significant improvement at all time points of follow-up ( P < .001). Young age ( P = .005), low weight ( P = .019), shoulder activity level ( P = .003), unilateral affliction ( P = .046), and higher baseline WOSI score ( P = .04) were associated with a better treatment effect. Cases with increased glenoid retroversion, posterior scapulohumeral decentering, and dysplastic bony glenoid shape showed a trend toward shorter treatment effect duration. No complications during the intervention or follow-up period were observed. Conclusion: The shoulder-pacemaker therapy concept is an effective treatment with rapid improvement and sustained outcome over the course of 2 years in patients with noncontrollable PP-FSI with previously failed conventional treatment. Young and more athletic patients with lower weight and unilateral pathology respond best to the treatment.

“…In addition, a recent metaanalysis revealed no significant benefits of shoulder ES for improving arm function 36 , 12 consistent with findings in this study. Some studies comparing EMG-triggered and passive distal stimulation also revealed no significant differences between the two modalities 12,13 . Our findings may be related to the fact that position-triggered ES used in this study did not incorporate an adequate level of cognitive efforts to improve neural plasticity for motor recovery after stroke 10,14 .…”

“…However, several randomized controlled trials showed no significant difference in motor recovery by EMG-triggered ES compared to that by passive ES [10][11][12][13] . EMG-triggered stimulation, which incorporates short cognition effort with quick relaxation after successful triggering, may not create an adequate temporal association of motor intention and stimulated motor response 14 .…”

“…Regarding causes of shoulder pain, reports are related to lesions of the rotator cuff tendons, central poststroke pain, lack of sensibility, unilateral neglect, spasticity, reflex sympathetic dystrophy, and inferior-anterior subluxation of the head of the humerus [1]. Glenohumeral Subluxation (GHS) is common in hemiplegic patients with shoulder pain [2]. GHS, closely related to upper limb function, is found most often in stroke patients [2].…”

“…Glenohumeral Subluxation (GHS) is common in hemiplegic patients with shoulder pain [2]. GHS, closely related to upper limb function, is found most often in stroke patients [2]. Although GHS is not typically accompanied by pain initially, as the patient continues in the flaccid stage or with injuries in soft tissues, pain may appear over an area half to two-finger widths at the shoulder joint [3].…”

Persistence of Glenohumeral Subluxation is Correlated with Prolonged Existence of Crossed Cerebellar Diaschisis in a Hemiplegic Stroke Survivor: A Pilot Study

Glenohumeral Subluxation (GHS) is one cause of shoulder pain after stroke. The greater the distance of GHS, the higher is the chance of rotator tendonitis or tearing of the tendon, causing limited motions and excruciating pain. Cross Cerebellar Diaschisis (CCD), a reduction of blood flow in the contralateral cerebellum after the supratentorial stroke, is detectable by a brain perfusion scan, and it has marked impacts on functional outcomes after stroke. We presented here a case on hemiplegic stroke. CCD of the patient persisted for 7 months without improvements. The patient underwent measurement of GHS and Single Photon Emission Computed Tomography to confirm the characteristic relationship. The patient’s GHS persisted for a prolonged period of time during which the acromiohumeral distance was longer than those of the general CCD-free stroke. Together with persisted CCD, the persistence of GHS was correlated with a prolonged CCD, which is presumably one sign of motor deficits associated with CCD.
